A cross support member is connected to bottom surfaces of the main frames in the region of the intermediate connecting section. This support member has opposite ends thereof extending laterally outwardly of the main frames. Outward extension of the cross support member include connecting elements for working implements. These connecting elements and the front frames are used as supporting connections for connecting working implements such as a front loader and a mower unit.
